Abstract

A new method for the identification of mononuclear and polynuclear complexes was derived based on the classical limiting logarithmic method and mole-ratio method. The method was aoolied to the La-ALC and Ce-ALC systems. Their stability constants of La2(ALC)2 and Ce2(ALC)2 (lg K2,2) are 14.70 and 15.84, resp. These results are in good agreement with those obtained by using the Gonzalez-Garcia's method.
